This talk will prese nt new impossibility results about classical problems in dynamical systems and ergodic theory. They answer questions dating to Poincaré and others a sked by von Neumann and Smale.\n\n\n \n \n \n Lien ZOOM Link\n \n \n \n\n DTSTART:20250328T193000Z DTEND:20250328T203000Z SUMMARY:Matthew Foreman (UC Irvine) URL:/mathstat/channels/event/matthew-foreman-uc-irvine -364438 END:VEVENT END:VCALENDAR
